Power Shell as admin? (Firefox) (or Windows)
How do I get there?
PowerShell allows you to use scripts and commands (replaced Command line) and is normally intended for Windows Server and Desktop Admins. Very much like Terminal is for Mac OS it allows you to change, delete items that are not easily accessible otherwise as well as run custom scripts to make short work of many tasks plus so much more. It can be destructive if not used properly. Use with caution!
In Windows 7 it is under Start/All Programs/Accessories/Windows PowerShell
